Il'nis invention relates to apparatus for cardboard. By the .aid of thisfeature of my operating on thin, fibrous material, such as invention,the task of setting up the ma- 55 paper board, whereby such material maybe chine for producing any spacing of lateral readily shaped to form abox-like container. creases, is very materially reduced.

it In the manufacture of boxes .made from Ihe longitudinal creases areproduced by comparatively stiii cardboard, it has been verticallyreciprocating dies cooperating customary to crease the cardboard, asbydies, with stationary dies and extending longi- 60 for the ready bendingor folding of the matudlnally of the cardboard travel. It is terial-intoa box form. Furthermorm'ithas another object of my invention to provideW been usual to form the entire box or carton a mechanism thatautomatically places the from a single piece of board, whereby it issheets of cardboard in succession between necessary to fasten only a fewotthe edges the relatively moving dies, and then expels t5 together,andin order that such a piece be them after the creasing operationis'comthus utilized, creases both lateral andlongipleted. In thisconnect1on,my invention is p tudinal must be made in the blank. In priornot limited to any particular kind of maschemes for forming the creases,separate terlal operated upon, nor-to any particular mechanism wasutilized" for each set of form of'dios, since it is obviously capable of70 creases, the board being passed manually by application to otherprocesses than that of an attendant .to each of the mechanisms. creasingbox blanks.

Such a procedure is not only uneconomical It is still another object ofmy invention from the standpoint of labor employed, but to'provideimproved mechanisms for eiiectit is also time consuming as compared withmg adJustment of the Various v which 75. the prpcedure rendered possibleby the aid mechanisms in themselves are novel and US8- of my invention.Itis thus one of the obf jects of my invention to provide ha- It 15still another ob ect of my mvention nism whereby the process ofpreparing the o provide a stamping or pressing mechabl k f b di g i tl filin1sm (such as a creasing or printing device) 80 mt' i I that may befed automatically by t e aid of I attain this object by making itpossible P PQ con eyor mechanism. u

It isanother object of my invention lowing description, where I shall outlinein 50 to make it possible to set the dies so that full that form of theinvention which I have the creases made thereby are properly disselectedfor illustration in the drawings actanced with respect to each other aswell as companying and forming part of the preswith respect to thetransverse edge of the ent specification.

Preliminary to the formation of creases in a blank, ll show apparatusfor printin advertising matter or the like thereon; an I associate theprinting press with the creasing mechanism so that a complete unit intandem is formed, whereby the pa er that is fed into the printin pressiselivered therefrom to the first e ement of the creasing mechanisms,whence it continues to travel through the machine and is finallydelivered at the other end. Since these mechanisms are associated inthis manner, theunit occupies considerablespace. in

the dies carried thereby at de- 011 the periphery, so as to prospacedapart by the proper view through the general, I shall outline theconstruction and general arrangement of the entire support ing structurehad better be referred to H1 somewhat cursory fashion.

This structure is best elucidated by consideration of Figures 5, 6, 7,and 8, representing mechanism extending respectively from 7 right toleft: The flooring 41 in this instance is shown'as of concrete, whichmay be a propriately reinforced to withstand the load imposed upon it.Furthermore the top surface may e-treated 'or covered in any appropriatemanner. columnar frames and supporting legs, for

example, such as the legs 42 (Fig. 5 These 0n this flooring rests 2supports serve to' hold not only the stationary parts of the mechanismbut also all of the movable parts, either directly or by the aid ofbearings located thereon. Beneath the flooring, several rotatablymounted shafts such as 44 and 45, are supported'and serve to performcertain adjusting functions which will be det'cribed in detail later.Appropriate bearing blocks 46, 47, 48, 49, 50, 51, 52 and 53 aresupported beneath flooring 41 for these shafts, and small electricmotors 54 and 55 operate these shafts as desired through reductiongearing 56, 57.

The main source of power for the mechanism is derived from a motor 58shown in Fig.

2, which is located beneath the main platform of the machine or in anyotherconvenlent place. This motor is connected to drive the main driveshafting 59, through various double roller type,

fill

power transmitting devices, such as the belt 60, pulyeys 61 and 62,counter-shaft 63, and gearing 64. Since the details of the drive formno. part of the present invention,] shall describe no further elementsthereof at this time, other than to mention that in view of the-longaxial. length ofshafting 59, l find it convenient to make it in sectionsunited by couplings such as 65. This main sbafting 59, as 'wellas shafts44 and disposed below the machine,entend longitudinally thereof asuflieient distance to per;

form their functions satisfactorily.

The printing press 66 (Figs. Land 5) be-- ing in this instance the firstto operate on the rectangular carboards that later constitute the boxblanks, is located at the right hand end of the machine. It may be ofany standard construction; in this instance of the and is supported on a-rigid frame 67 placed on flooring 41. The drive for the cylinders isaccomplished by the aid of shaft 68 driven from main shafting 59 by theaid. of the bevel gearing 69. This shaft'68 is in turn geared" orotherwise connected to the roll shafts 7 0 and 71. These platens,

latter shafts carry the impression which are adjustable in astandardwith respect to therollers in a conventional manner con'unon to thepainting-press art. Feed and discharge rolls are also appropriatelydriven "at the front and rear of the press, by the aid of mechanismgenerally indicated at 7'2 and 73. In F ig. 5 other parts of themechanism are disclosed, but in yiew that the present invention residesin. part in the correlation of the entire press to the other elementsof'the machine, it is deemed (ill r sprocket wheel. 77.

the printing platen;

passes the conveyor chain T4, which loops over the idler wheel 79 at theright hand end of the machine. The cardboard to be printed is depositedon this conveyor chain, which runs in a slot in the center of the and inorder that this chain paper positively forward, 1

pushers 78 fastened to links in therhain 74 which engage the cardboard80' (F ig. 14-) at its right hand edge. The length of the conveyor chain74 is purposely chosen to be an even multiple of the circumference ofthe may move the provide several.

ers 78 have their active surfaces spaccu apart by the length of thiscircumfercmre; in addition, the drive-for the chain is so propor-'tioned that for each revolution ofthc printing rollers, the chain T4 isadvanced by an amount equal to the length of the roller circun'iference.in view of this arrangement. it is ensured that the printed matter willappear on each sheet. of cardboard in ,substantially the same positionwith respect to the transverse edges of the sheet. The sheet 80 isguided at its longitudinal edges by the angle guide plates 81. 'Theseplates are adjustable to ace unmodate varying widths of sheets, as bythe aid of the square-thread studs 82 fastened at their inner ends tothe plates 81, as shown in Figure 1; and the gltgide rods-B3 whichensure parallel mot' n of the plates 81. These rods pass slidablythrough stationary posts 84. The studs 82 may be simultaneously movedaxially tomove the plates 81 either toward or from each other by the aidof a hand crank 85 (Fig. 5) fastened to one of the ronuts 87 threaded onthe studs and held against axial movement by the stationary standards 86through which .the studs pass; and motion transmitting mechanism 1between the studs, comprising the sprocket,- chains 88 passing oversprocket teeth on the nuts 87, shaft 89, and sprocket wheels 90 fastenedto said shaft. As thus described, it is evident that rotating handle 85will cause simultaneous rotation of nuts 87, and consequent axialmovement of studs 82. As the sheet 80 advances between the guides 81',its front edge is prevented from curling upward by theslanting guardplate 91 (Fig. 5), havinga lower edge near the top surface of theconveyor chain 74 opposite the bite of the feed roller device 72.

Of course the position of the printed matter relatively to the lateraledges of sheet 80 is determined by the relation of the pushers 7 8 withrespect to a reference point at any place on the printing rollerperiphery that happens to be in its lowermost, printing position. Thisrelation may he adjusted by properly adjustng the angular position ofbut for the sake of ease in adjustment, prefer to accomplish this resultby adjusting the pushers 7 8 with retable 43 and the push is in motion.For this purpose I have constructed a device for angularly adjusting thedriving sprocket 77 with -respect to the.

This mechanism is mostaxis of shaft 76. clearly illustrated in Figures10, 11, 12, 13, and 14.

As shown in Figure 12, the sprocket wheel 7 7 is not keyed to shaft 76butwould be free to rotate thereon were it not for an adjustableclutching device which will nowbe described. The main elements of theclutch are the worm wheel 92 keyed to shaft 76, and a worm 93 carried onthe side of the wheel 77 and meshing with the wheel 92. This worm 93 isso supported on wheel 7 7 that rotating it will cause the wheel 77 tomove angularly with respect to wheel 92. The support for this worm isbest disclosed in Figs. 11 and 12; A standard 94 is bolted to the sideof wheel Why the aid of the through bolt 95, which passes through alarge clearance hole inthe base of standard 94, and the screw 99 thattaps intoa boss 100 carried by the standard 94 and journaled in the hole101 in'wheel 77. This standard carries at its ends the journals 96 and97 in which the worm shaft 98 rotates. The accurate adjustment of theworm 93 relative to wheel 92 is secured by the aid of set screws 102that pass through lugs 103 on wheel 77 and engage opposite sides ofstandard 94 near that place where the through bolt 95 is located. Thisadjustment of course takes place while this belt is loosened, and afterit is completed, the bolt is fastened in place.

bly of the device Rotation of-set screws 102, as-is evident, produces'arelatively small rotation of standard 94 about the axis of screw 99.-The bearing 96 is shown as formed internally of .a short screw'104 thattaps into the standard 94, for the purpose of permitting assemby passingthe worm 93 through the tapped hole in the standard. The other bearmg97extends through the standard 94, and accommodates the shank 105 of theworm 93. This shank extends en tirely through the bearing 97, and alsohas a collar 106 that keeps it inproper axial posito the hearing.

It is evident th can be secured by rotation of the worm 93. Furthermorethis worm serves as a mechanical connection between the two wheels 77and 92; and-the drive from worm 93 to wheel92 being of an irreversiblenature, there is no danger that this mechanicalconnection can slipafterthe angular adj ustmentis performed. Although it would be possible torotate the-worm 93 this result, I prefer to whereby the adjustmentsupplied from .geal'lng P by hand ,to secure shaft 76. For this purposesuch as to tive, the wheel 113 may being rotated.

, at angular adjustment of main sprocket wheel 77 vided between shaft 76and the worm 93,

'which may at will be rende'red'active. Thus loosely journaled on awhich is opposite to the view shown. To

hold the gears 108 and 110 against axial movement, a washer and nutarrangement 112 is provided.

The spur gear 110'is in mesh with a gear 113 that is arranged axiallywith respect 1 to shaft 7 6; and if this gear be held stationary, it isevident that the'planetary'movcment of gear 110 will cause this lattergear to rotate about its own adjustment of the worm 93. However, duringnormal operation, the gear 113 is rotated as fast as gear 110 revolvesin its planetary path, by being in driving-connection with shaft 76.Under such circumstances there willbe no relative movement of gears 110and 113. The shaft 76 and gear 113 are connected by a spline connection114, which is ment at will, betweenthem. For example, in the full lineposition of Figure 12, the spline connection is active to cause rotationof wheel 113. To render this connection inacwar'd toward gear 92 to thedotted line position. where the splines 114 on shaft 76 are passedbeyond the corresponding slots in the hub of gear 113. The face of thisgear 1s made wide enough to cause it to be malntained in mesh with gear110 for both positions. The gear 113, when in dotted line position, maybe manually held against rotation, and thereby .to serve analogously toa stationary rack on which tate. When this is done, the worm 93 is Theaxial movement of gear 113 is" accomplished by thelaid of a rod 115which is fastened at its inner end to the extended hub of wheel 113, asby the aid of the (pm 116.
